59 i-is iiiiiii? 1G tact with the cylindrical portion of the carrier, as shown by .the dotted lines h in Fi 5.

K notch m is formed in the back of the carrier to permit the crowding of the blade outwardly from the flan es when it'is necessary to remove the bla e.

The handle 12. is formed with a screw-end 0 having a shoulder pat its base, and such screw-end is adapted to'fit interchangeably the nuts upon the razor-body and upon the blade-carrier. A guide-pin 0 is formed upon the end of the screw 0 and made to fit snugly the interior of the threads, so as to gui e the thread accurately in entering the nut and prevent the stripping or wear which results om crowding the screw into the thread of the nuts unevenly.

A latch is provided movably upon the shoulder to lock the handle in either of the nuts upon the blade-c: rrier so as to hold the blade-carrier firmly when moved by the handle in'stroppin the blade. The latch is shown .15 a spring olt projecting from the shoulder and operates automatically to engage a notch' upon the face of the nut;

The bolt q is fitted to a socket extended.

into the shoulder and rests upon a spring 1' inthe bottom of the socket. A thumb-piece s-iS provided in therouter side of the bolt by which the thumb-nail can retract it.

A notch t is formed in theouter end of each nut and the bolt projects from the shoulder p sufiiciently'to engage the notch when the end 0 is screwed nearly into the nut. The spring operates to press the bolt automatically into the notch so as to engage the same when the shoulder has approached closely to the notched face of'the nut.

To permit the shoulder to be screwed close to the nut, the bolt may be retracted by the finger and held from enterin the notch t until the shoulder is crowde against the nut, as shown at p in Fig. 5.

The construction of the bolt and its retention in the socket is facilitated by: making the body of the handle n with a socket at its outer end and mounting the bolt in a shank n which is inserted almost wholly in such socket.

The groove for the bolt extends to-the side of the shank, and it may thus be laid in the groove between the spring 1* and the end of the groove, and then held in place by fitting the shank into the socket in which it is permanently v secured. 1

It is obvious that the blade can be stropped if the blade-carrier has a nut j in one end only, but the provision of two nuts enables the operator to remove the bladefrom the razor-head in either direction that he .may prefer, thus accommodating either righthanded or left-handed persons.

rier w It will be observed that the hollow cylindrical back'of the blade-carrier enables it to perform two functions, first, to receive cylindrical nuts in the ends, where they are readily held by solder; and second, to fit the cylindrical bore in the body or razor-head.

A particular construction of the clampplate 0 is shown in Fig. 3 with the purpose of guarding the blade more effectively when used in shaving.

The forward edge of the clamp-plate is extended close tothe edge of the blade, to permit only a small projection of the blade between the clamp-plate and the comb so that the tipping of the razor at an improper angle either upward or downward brings the comb or clamp-plate in contact with the skin and prevents the cutting edge from operating. This extension of the clampplate close to the edge of" the blade thus forms a considerable safeguard in the use of the razor;

It will be observed in Fig. 3, that the comb-plate a bears a'relation to the razorblade wholly different from the clamp-plate I, or any construction in which'the edge of the blade is carried by projecting through a mere slot. The edge of the comb-plate a curved away from the blade so that it may rest and more smoothly upon the skin of the user to support the razor in the shaving operation; but the clamp-plate c is not curved away from the razor-blade but lies close to it, and extends close to its edge so as to contact with the skin at intervals whenever the operator tips the razor-head to an unsafe angle. Each of these parts thus guards the edge of the razor in a different manner.

I am aware that razor-heads and bladecarriers have been formed of sheet metal, and that a razor-handlibhas been fitted inter changeably with the razor-head and razorblade, though not by the means shown herein, and I do not therefore claim such constructions broadly, but the particular features of construction which are defined in my claims.

Having thus set forth the nature of the invention what is claimed herein is:

1.. In a safety razor, the combination, with a blade-carrier having a hollow cylindrical back with. elastic gripping flanges extended therefrom, and a cylindrical nut secured within the end of the back, of sloping projections upon the inner side of one of the flanges at 1ts corners, and a razor-blade having anotchin its inner corner to clear-the said nut and pressed-elastically upon by the slopingl projections to retain it-in the caren inserted into the back from the front edges of the flanges.

2. .In asafety razor, the combination, with a blade-carrier formed of sheet-metal with a hollow cylindrical back and gripping flanges extended from one side of the same to carry a razor-blade, of a nut secured in the end of the back having a notch in its outer end, and a handle having a screw and shoulder to engage such nut with a latch movable upon the shoulder adapted to automatically engage the notch as the shoulder approaches the face of the nut.

3. A safety razor, having a body comprising a comb and clamping-plate united by a loop and having opposed curves adjacent to the loop forming a cylindrical bore, a sheetmetal blade carrier having a cylindrical back with gripping flanges to carry a razorblade, a handle having a screw and shoulder near the end, nuts upon the body of the razor and in the end of the blade-carrier to interchangeably fit the screw upon the handle, the nut upon the blade-carrier having a notch in its outer face and a latch movable upon the shoulder to automatically engage the notch in the nut to hold the handle from rotation.

4. A safety razor having a body comprising an integral comb and clamping-plate with a nearly cylindrical bore near their junction, at sheet-metal blade-carrier having a hollow cylindrical back with gripping flanges to carry a razor-blade, a nut secured in the end of the back having a notch in its outer face, another nut upon the body of the razor, a handle having a screw and shoulder to interchangeably engage such nuts, a boltsocket extending inwardly from the shoulder with a spring in the bottom thereof, a sliding bolt fitted to the socket upon the spring and adapted to engage the notch in the nut, and a thumb-piece for retracting the bolt to disengage the handle from the nut.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
